.dppllcetion filed November 9, 1301. Serial No. 81,766.

fill; all? whom it may concern Be it known that L Lanszxs Oxnnnnomr, a citizen of the United States, residing at New, York, in the county of New York, State of New York, have invented certain thread, and the object of the invention isto provide a simple and effective devicefor pulling; of? thread from the spools to supply lit) = 'tions hereinafter the needle at the proper time; and also in the upward movement of the needle to take up the slack in the needle thread caused by Y the ascent of said needle, thus enabling all the superfluous thread to be taken out. and the stitch to be properly drawn up,

"in one of its phases, the invention consists in providing a. take-up for the needle thread, which is operated independently of the needle bar, it being for convenience attached to the oscillating looper supporting shaft co'ciperating with stationary eyelets to pull; oli thread from the spools sufiicient tor the needle to use up in its downward .ioveinent, and to take up the superfluous "thread the upward movement of the needle.

idecondly, the invention consists in pro riding a take-up for the needle thread, independent of the needle bar or needle opcrating mechanism, and comprising an oscillating shaft arranged above the cloth plate of the machine, and having a traveling arin cotiperating with thread guiding eyelets, which arm pulls off thread from the spools suiiicient for the needle to use up in its downward movement, and which takes up this slack as the needle is moving upwardly.

Finally, the invention consists in the various details of-construhtion and combinareferred to in .the appended clziin s;

' l The invention is illustrated in the-accorn- 1 panying drawings, in which- Figure 1 represents a front view of so inuch'ofli a sewing; machine as is necessary plete understanding offmy invena skeletonized view, showing and useful Improvements in 0verseamis oscillated, carrying the looper point in rear of and to'one side the necthe manner of operating the loopcr an d takeup; and Fig. 3 is a plan view ol Fig. 2.

' l n these drawings, the thread-carrying eye-pointed needle l, is of ordinary construction, rind operates in the usual. manner from the driving shaft A, through the needle lever B.

C represents a looping hook or spreader supported on double cranks, and operated by a pitinan connection D from the needle lever extension D. This spreader has a hook at its upper end, and reciprocates in the manner shown in the drawings, to catch loop of needle thread, carryii'ig it to one side, and up shore the throat plate into position to be entered by the loopw E, as it moves from the rear toward the front of the needle in a curved inclined path.

The looper E is a thread-carrying looper, and its upper end or shank is secured in a collar l" clamped to the lower end of the shaft (.l, which is arranged at an inclination to the cloth plate, and slightly oil the vertical, passing through openings in the head of the machine, which form hearings J, 3, for it. At its upper end, the loopcr supporting shaft is fitted into the socket of a clamping head or block H, provided at its upper end with a. ball stud. l, over which loosely fits a head hi, to which one end oi. the pitinan rod L, is attached. This pitinan rod L at its opposite end is screwed into a. socket on i! head ld fitting a ball stud N, carried upon the end oi. the vertical arm 0 of the bell crank lever, pivoted at l to the machine standard. The horizontal arin Qyo'l' said bell crank lever carrics a hall stud, upon which is fitted a head R, upon the upper end of the connecting rod S, which embraces the eccentric 1, upon the driving shaft of the machine.

In the rotation oi the driving shaft, the inclined shaft which supports the loopcr from a.

dle, ar und in a curved path inclined to the cloth plate, through the needle loop which has been brought by the spreader or looping hook up into the path of said loopcr and around in front of the needle, so that the needle in its descent passes through the loop carried on the loopcr, thus making an overedg'e stitch.

Adjustabl y attached to the clan'ipinp; hca d or block H, in which the upper end oz 5:,

V passing through said eyelets to a and said eyelet-supporting arm is at its lower end connected by a link (5 to the needle bar head or gate 7., The plate 4 has a projecting arm 4*, at the forward end of which is an eye or opening 8, through whichthe thread is guided between said two eyelets. From the second eyelet above referred to, the thread is guided to another stationary eyelet 9 on the upper needle bar lug, and from there the thread extends to the eye of the needle in the usual way.

It will thus be seen that I have provided a thread controller comprising spaced thread eyelets between which is arranged an oscillating thread guide which moves from a position adjacent one of said eyelets toa osition adjacent to the other thread eyelet and the movements of said thread guide are such that it intersects a line passing through said eyelets at two places which are respectively adjacent said eyelets. It will also be seen that the extreme positions of said thread guide are on one side of the line passing through the eyelets. my referred arrangement of parts, it will be oliwions that said thread guide may be solocated relative to the thread to move from a position on one side of a line position on the opposite side of said line. tis essential however, that said thread guide should move from a position closely adjacent oneof said thread'eyeletsto a position closely adjacent to theotherthread eyelet. The action of the'thread guide upon the thread passing through the thread eyelets is as follows: Assuming that the needle is in its extreme upward position, and at this time the spreader carrying the needle loop around the edgeof the material is holding the needle loop for the entrance of the thread so that drawn from the supply.

looperand the looper has moved forward with its point just entering the needle loop carried by the spreader. The thread guide is moved toward the thread eye 6 and is just engaging the thread for the pulling 0d action. The movement of the spreader has at this time taken all the slack out of the as the needle begins its downward movement, the thread is under tension and the movement of the thread guide toward the eyelet 6, operates to pull thread from, the supply. T he downward movement of the needle together with the forward movement of the looper, holds the thread taut during this movement of the thread guide and therefore, thread is necessarily After the point of While this is eyelets as guide is moved into contact with the thread at a point adjacent the threadeyelet 5 and y a further movement of this thread guide, the needle thread will be taken'up, for at this time the needle thread is slack. It will thus be seenthat the thread guide in its movement from a position adjacent one thread eyelet to the other, operates to pull off suiiicient thread from the supply for the formation of the stitch in one of its movements and to take up the slack in the thread in its other movement.

It will be noticed that the needle thread take-up is independent of the needle bar and its operating parts, and while the operation of this pull-off and take-up by the looper supporting shaft is herein claimed as a feature of the invention, it will be understood that the pull-off and take-up may be applied to any suitable oscillating shaft arranged above the bed plate of the machine, and I do not, therefore, wish. to be limited, so far as the broad claims of my application are concerned, to any specific details of construction, as 'various modifications and changes may be made, without departing from the spirit of my invention.
